Whenever I subscribe to a new feed on Google Reader I can choose a folder for it and that's the only way I see for adding a tag to that subscription. It makes me wonder why Google insists on confusing us using both folders and tags to refer to what it seems to be the same thing.

Other feed readers, like Rojo, allow you to add many tags at once by just writing them, on the same way you can add tags to photos on Flickr. I've used Rojo before but I really prefer Google Reader now.

Am I correct on assuming that the only way of adding more tags to a subscription on Google Reader is by going to Settings, Subscriptions and then checking the subscriptions and choosing a tag from the more actions list?

Don't we have an easier way? I hope I'm missing something really obvious here.
